This study tested longitudinal associations between absolute levels of perceived partner responsiveness (PPR; how much people perceive that their romantic partners understand, care for, and appreciate them), daily negative affect reactivity and positive affect reactivity, and all-cause mortality in a sample of 1,208 adults for three waves of data collection spanning 20 years. We also tested whether longitudinal changes in PPR predicted mortality via affect reactivity.
Data were taken from the National Survey of Midlife Development in the United States. PPR was assessed at waves 1 and 2, affect reactivity to stressors was assessed by daily diary reports at wave 2, and mortality status was obtained at wave 3.
Mediation analyses revealed absolute levels of PPR at wave 1 predicted wave 3 mortality via wave 2 affective reactivity in the predicted direction, but this did not remain robust when statistically accounting for covariates (e.g., marital risk, neuroticism), β = .004, 95% confidence interval = -.03 to .04. However, wave 1-2 PPR change predicted negative affect (but not positive affect) reactivity to daily stressors at wave 2, which then predicted mortality risk a decade later (wave 3); these results held when adjusting for relevant demographic, health, and psychosocial covariates, β = -.04, 95% confidence interval = -.09 to -.002.
These findings are among the first to provide direct evidence of psychological mechanisms underlying the links between intimate relationships and mortality and have implications for research aiming to develop interventions that increase or maintain responsiveness in relationships over time.
本研究检验了在一项为期 20 年的三波数据收集的样本中,个体感知到的伴侣反应性(PPR;人们感知到其伴侣理解、关心和欣赏自己的程度)的绝对水平与每日负性情绪反应性和正性情绪反应性之间的纵向关联,以及与全因死亡率之间的关系。我们还检验了 PPR 的纵向变化是否通过情绪反应性预测死亡率。
数据来自美国全国中年发展调查。PPR 在第 1 波和第 2 波进行评估,对压力源的情绪反应性通过第 2 波的每日日记报告进行评估,而死亡率状态在第 3 波获得。
中介分析显示,第 1 波的 PPR 绝对水平通过第 2 波的情绪反应性预测了第 3 波的死亡率,这在统计学上考虑到协变量(如婚姻风险、神经质)时仍然稳健,β=0.004,95%置信区间为-.03 到 -.04。然而,第 1 波至第 2 波的 PPR 变化预测了第 2 波对日常压力源的负性情绪(但不是正性情绪)反应性,而这又预测了 10 年后的死亡率(第 3 波);当调整相关的人口统计学、健康和心理社会协变量时,这些结果仍然成立,β=-.04,95%置信区间为-.09 至 -.002。
这些发现是首批直接提供亲密关系与死亡率之间关系的心理机制的证据之一,对旨在开发随着时间的推移增加或维持关系反应性的干预措施的研究具有启示意义。
